If you have 5.25 grams of methane (ch4), how many grams of co2 will you produce ?

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
